The substrate 110 has a bonding region 112 and a sensing region 114 that are adjacent to each other in the first direction D1. First sensing rows 120 are arranged in parallel within the sensing region 114. The second sensing row 130 is also arranged in parallel within the sensing region 114. Each first line 140 extends to the bonding region 112 in connection with the first sensing row 120. The second lines 150 are each connected to the second sensing row 130 and extend to the bonding region 112. Each of the first sense columns 120 extends along a first direction D1, each of the second sense columns 130 extends along a second direction D2, and the first direction D1 is a second direction. Crosses D2. In the present embodiment, the first direction D1 is perpendicular to the second direction D2. However, in other embodiments, the first direction D1 and the second direction D2 may not be perpendicular to each other. Further, the plurality of pads 160 are disposed in the bonding region 112, and the first lines 140 and the second lines 150 extend to the pads 160, respectively. Nevertheless, in other embodiments, one end of the first line 140 and the second line 150 extending to the bonding region 112 is directly connected to a circuit board or external circuit to be considered as a pad.

The Therefore, the space region G shows the lattice-like distribution of FIG.

Since the bonding region 112 is adjacent to the end of the first sensing row 120, the bonding region 112 extends from the first sensing row 120 to which each of the first lines 140 is connected along the first direction D1. It extends outward. Each of the second lines 150 also extends from the connected second sensing row 130 to the bonding region 112. However, in the present embodiment, each of the second lines 150 is arranged along the space region G. Therefore, each of the second lines 150 is bent along the space region G in a zigzag shape. In the present embodiment, each second electrode portion 132 of the second sensing row 130 includes two terminal electrode portions 132A and at least one intermediate electrode portion 132B, and the intermediate electrode portion 132B includes two terminal electrode portions. It is arranged between 132A. On the other hand, all of the second lines 150 are disposed between the terminal electrodes 132A of the second sensing row 130.

A sixth second sense train 130F connects to the second lines 150A-150F, respectively. Accordingly, the second line 150B connected to the second second sensing column 130B intersects one of the second intersections 134 of the first second sensing column 130A. The second line 150C connected to the third second sensing row 130C includes the second intersection 134 of the first second sensing row 130A and the second of the second second sensing row 130B. Intersects one of the intersections 134. Accordingly, the second line 150F connected to the sixth second sensing row 130F is connected to one of the second intersections 134 in each of the first to fifth second sensing rows 130A to 130E. Intersect.

In the present embodiment, the first sensing row 120 and the second sensing row 130 intersect each other, but the first sensing row 120 and the second sensing row 130 are used to implement a touch sensing function.

Part 134 is made from the second layer. The first layer and the second layer are separated by an insulating layer 170. More specifically, the insulating layer 170 is disposed at a portion where at least the first layer and the second layer intersect. In other words, the insulating layer 170 may be a plurality of island-shaped insulators positioned between the first intersecting portion 124 and the second intersecting portion 134 that intersect each other.

In this embodiment, the second line 150 connected to the second sensing row 130 may also be made from the first layer. Referring to FIG. 1, a part of second line 150 intersects a part of second intersection 134. Therefore, the insulating layer 170 may be disposed between the second line 150 and the second intersection 134 that intersect each other. As a result, the relationship in which the first sensing row 120 and the second sensing row 130 are electrically independent from each other may be realized by disposing the insulating layer 170.

The first sensing row 120, the second electrode part 132, and the second line 150 are made of the first layer and can be manufactured in the same manufacturing process. Therefore, even though a part of the second line 150 is arranged to intersect a part of the second intersection 134, it does not complicate the overall manufacturing process. Instead, the second lines 150 arranged and distributed along the space region G can provide a fine edge for the touch panel 100, or can realize an edgeless design.
